// 创建'外壳'组件
// { Component }，react使用多种暴露
import React, { Component } from "react";
import Hello from "./components/Hello";
import Welcome from "./components/Welcome";

// 创建并暴露App组件
export default class App extends Component {
  render() {
    return (
      <div>
        <Hello />
        <Welcome />
      </div>
